The two have maintained that they are friends and have a business relationship -- plus
Flajnik says he has a girlfriend. But
US Weekly has a source saying, "They started hanging out. It got romantic right away. They've been hooking up."

However, Flajnik continues to dispel the rumors, writing on
Twitter, "Here we go again. Hey @usweekly maybe put a call into me once and a while for some fact checking. Sincerely, #TheTruth."

US fires back that they reached out to Flajnik over email and all he wrote back to them was, "Oh, jeez, ha. I'm over this."

The magazine also says that the "hooking up" started way before the official Jenner separation announcement. According to the magazine, the two started "a fling" back in July after he appeared on her daytime talk show "Kris."

What do you think? Making a mountain out of a molehill? Or where there's smoke, there's fire?
